Risk of atrial fibrillation development in adolescent patients with inflammatory bowel disease.

There is increasing evidence linking chronic inflammation to the initiation and continuation of atrial fibrillation (AF). Inflammatory bowel diseases (IBD), namely (Crohn's disease (CD) and ulcerative colitis (UC), are chronic systemic inflammatory disorders with both intestinal and extra-intestinal manifestations. Atrial electromechanical delay (EMD) has been known as an early marker of AF. The objective of this study was to evaluate the atrial electromechanical properties in children and adolescents with IBD during remission. One hundred IBD patients aged 12-17 years (50 with CD and 50 with UC) in remission state and 100 healthy controls were recruited for the study. Atrial electromechanical properties were measured using transthoracic echocardiography, tissue Doppler imaging, and simultaneous surface ECG recording. Interatrial EMD, left intra-atrial, and right intra-atrial EMD were calculated. IBD patients in remission state have significantly prolonged left and right intra-atrial EMD and interatrial EMD compared to healthy controls (P = 0.03, P = 0.02, and P = 0.01 respectively). No statistical difference was observed between CD and UC in terms of inter- and intra-atrial EMDs.  Conclusion: Atrial EMD is increased in pediatric patients with IBD indicating the increased risk of AF development. Measurement of atrial EMD parameters might be used to predict the risk of the development of AF in pediatric patients with IBD. What is Known: • There is increasing evidence linking chronic inflammation to the initiation and continuation of atrial fibrillation (AF). • Inflammatory bowel diseases are chronic systemic inflammatory disorders with both intestinal and extra-intestinal manifestations. • Atrial electromechanical delay (EMD) has been reported as an early marker of AF. What is New: • Atrial EMD is increased in pediatric patients with IBD indicating the increased risk of AF development. • Measurement of atrial EMD parameters might be used to predict the risk of the development of AF in pediatric patients with IBD.

Renal calcification in children with renal tubular acidosis: What a paediatrician should know .

Renal tubular acidosis (RTA) can lead to renal calcification in children, which can cause various complications and impair renal function. This review provides pediatricians with a comprehensive understanding of the relationship between RTA and renal calcification, highlighting essential aspects for clinical management. The article analyzed relevant studies to explore the prevalence, risk factors, underlying mechanisms, and clinical implications of renal calcification in children with RTA. Results show that distal RTA (type 1) is particularly associated with nephrocalcinosis, which presents a higher risk of renal calcification. However, there are limitations to the existing literature, including a small number of studies, heterogeneity in methodologies, and potential publication bias. Longitudinal data and control groups are also lacking, which limits our understanding of long-term outcomes and optimal management strategies for children with RTA and renal calcification. Pediatricians play a crucial role in the early diagnosis and management of RTA to mitigate the risk of renal calcification and associated complications. In addition, alkaline therapy remains a cornerstone in the treatment of RTA, aimed at correcting the acid-base imbalance and reducing the formation of kidney stones. Therefore, early diagnosis and appropriate therapeutic interventions are paramount in preventing and managing renal calcification to preserve renal function and improve long-term outcomes for affected children. Further research with larger sample sizes and rigorous methodologies is needed to optimize the clinical approach to renal calcification in the context of RTA in the pediatric population.

Functional Thenar Reconstruction: A Case Report and Systematic Review of the Literature.

ABSTRACT: Reconstruction of the thumb is among the most complex challenges faced by hand surgeons. Meaningful functional recovery of the thumb is dependent mainly on thumb opposition and palmar abduction. Free functional muscle transfer provides neurotized, robust soft tissue coverage that can achieve dynamic reconstruction of thenar musculature in a single stage.We present a case of a free neurotized segmental gracilis muscle transfer for thenar reconstruction and a systematic review of thenar reconstruction with free functional muscle transfer in the literature. A teenage male patient with a gunshot-induced thenar defect was reconstructed using a free neurotized gracilis muscle measuring 5 × 11 cm. The obturator nerve was coapted to the recurrent motor branch of the median nerve. The patient reached M4 strength at 10 months with functional use of his thumb. A systematic review of options for functional thenar reconstruction revealed 14 studies describing functional thenar reconstruction in 44 patients. Successful functional flaps described included gracilis muscle, pronator quadratus muscle, pectoralis minor muscle, abductor hallucis muscle, extensor digitorum brevis muscle, and serratus anterior muscle. Microsurgical transfer of a functional muscle is an excellent option for single-stage thenar reconstruction of both form and function. There are a number of available donor sites with equivalent size and bulk to that of native thenar musculature.

Effects of adherence to the Mediterranean diet in children and adolescents with irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome (IBS) is a highly prevalent gastrointestinal disorder in children and adults, which increased over the past twenty years. The Mediterranean diet is a well-known diet full of antioxidants and anti-inflammatory ingredients. AIM: To evaluate the safety, tolerability, and effects of adherence to the Mediterranean diet on disease patterns in children and adolescents with IBS. METHODS: This prospective, cross-sectional case-controlled study included 100 consecutive IBS patients diagnosed according to Rome IV criteria, aged 12-18 years. Patients were subdivided into two groups (50 patients each); Group I received a Mediterranean diet, and Group II on their regular diet for six months. Besides IBS scores (IBS-SSS, IBS-QoL, and total score), different clinical and laboratory parameters were evaluated at the start and end of the study. RESULTS: The Mediterranean diet was safe and well-tolerated in IBS patients. IBS children and adolescents with good adherence to the Mediterranean diet (KIDMED Score ≥ 8 points); group I showed significant improvement in IBS scores. IBS-SSS in the Mediterranean diet group was 237.2 ± 65 at the beginning of the study and decreased to 163.2 ± 33.8 at the end of the study (P < 0.001). It did not show a significant improvement in the group with a regular diet (248.3 ± 71.1 at the beginning of the study compared to 228.5 ± 54.3 at the study end with P < 0.05). The mean IBS-SSS in the Mediterranean diet group significantly improved compared with the group with a regular diet. Mean IBS-QoL in group I improved from 57.3 ± 12.9 at the start of the study to 72.4 ± 11.2 at the study end (P < 0.001) and significantly improved when compared to its level in group II at the study end (59.2 ± 12.7 with P < 0.001), while group II showed no significant improvement in IBS-QoL at the study end when compared to the beginning of the study (59.2 ± 11.7 with P >0.05). The mean total IBS score in group I became 28.8 ± 11.2 at the end of our study compared to 24.1 ± 10.4 at the start (P < 0.05) and significantly improved when compared to its level in group II at the end of the study (22.1 ± 12.5 with P < 0.05), while in group II, non-significant improvement in the total score at the end of our study compared to its mean level at the start of the study (22.8 ± 13.5 with P > 0.05). CONCLUSION: The Mediterranean diet was safe and associated with significant improvement in IBS scores in children and adolescent patients with IBS.

Adherence to the Mediterranean Diet Improved Clinical Scores and Inflammatory Markers in Children with Active Inflammatory Bowel Disease: A Randomized Trial.

Objective: The Mediterranean diet (MD) is a well-known style of diet that is full of antioxidants and may have anti-inflammatory effects. We evaluated the safety, tolerability, and effects of adherence to MD on disease activity and inflammatory markers in children and adolescents with active inflammatory bowel disease (IBD). Methods: This prospective, randomized study included 100 IBD patients aged twelve to eighteen years with mild to moderate disease activity (PCDAI score 10-45 or PUCAI 10-64). The included patients were divided into two groups of 50 patients each. Group I (26 patients with active CD and 24 patients with active UC) received MD with good adherence over 12 weeks with a KIDMED 8-point score, and group II (28 patients with active CD and 22 patients with active UC) received their usual diet with a KIDMED score ≤7 points. Patients in both groups received treatment similar for IBD activity. Results: Clinical remission was achieved in most of the patients after 12 weeks of treatment. Patients in the first group (adhering to an MD) showed a significant decrease in both clinical scores (PCDAI and PUCAI) and most inflammatory markers (CRP, calprotectin, TNF-α, IL17., IL 12 and IL13) compared to patients in their normal group, with earlier improvement in both PCDAI and CRP. Conclusion: Adherence to the MD improves clinical scores and inflammatory markers in children and adolescents with mild-moderate active IBD.

Pulmonary function test abnormalities in children and adolescents with non-alcoholic fatty liver disease.

Association between pulmonary function tests (PFTs) and non-alcoholic fatty liver disease (NAFLD) has been reported in adult studies; however, there is lack of pediatric studies. Our study aimed to evaluate PFTs in children with NAFLD. A total of 137 children with NAFLD and 100 healthy children of matched age and sex were included in the study. Different PFTs including forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, residual volume (RV), and total lung capacity (TLC) were performed for all included children. Lipid profile, insulin resistance, fasting and postprandial glucose level, and high sensitive C reactive protein (hs-CRP) were measured. FEV1 %, FVC %, FEV1/FVC ratio, RV, and TLC were significantly lower in the patient group compared with the control group (P < 0.05), while RV and hs-CRP were significantly higher in children with NAFLD. Restrictive lung dysfunction was the commonest pulmonary dysfunction detected in children with NAFLD (21.9%). PFT indices were significantly correlated with grade and duration of NAFLD, insulin resistance, waist circumference, and hs-CRP. Regression analysis revealed that insulin resistance and hs-CRP were independently associated with decreased PFT indices.Conclusion: PFT indices were impaired in children with NAFLD and this impairment was independently associated with insulin resistance and hs-CRP. What is Known: • Pulmonary function tests (PFTs) abnormalities are common in adults with nonalcoholic fatty liver disease (NAFLD). • Studies involving PFTs abnormalities in pediatric NAFLD are lacking. What is New: • It is the first study that assessed PFT in pediatric patients with NAFLD. • PFTs abnormalities are present in children with NAFLD. • Insulin resistance and high sensitive C reactive protein are independently associated with the decline of PFTs in children with NAFLD.

Preliminary Outcomes of Hypochlorous Acid as an Adjunct for Pocket Irrigation in Revision Aesthetic Breast Surgery.

BACKGROUND: Capsular contracture is a challenging problem for plastic surgeons despite advances in surgical technique. Breast pocket irrigation decreases bacterial bioburden. Studies have shown that hypochlorous acid (HOCl; PhaseOne Health, Nashville, TN) effectively penetrates and disrupts biofilms; however, there are limited clinical data regarding this irrigation in breast augmentation. OBJECTIVES: The aim of this study was to investigate the effects of HOCl pocket irrigation in revision breast augmentation by evaluating rates of capsular contracture recurrence, infection, and allergic reactions. METHODS: We performed an institutional review board-approved retrospective chart review of revision breast augmentation cases for Baker grade III/IV capsular contractures in which pockets were irrigated with HOCl. Data were obtained from 3 board-certified plastic surgeons. RESULTS: The study included 135 breasts in 71 patients, who ranged in age from 27 to 77 years (mean, 53.7 years). Follow-up ranged from 12 to 41 months (mean, 20.2 months). Postoperatively, there were 2 unilateral Baker grade III/IV recurrences at 13 months and 1 bilateral Baker grade II recurrence at 3 months. There were no infections or allergic reactions. The overall Baker grade III/IV capsular contracture recurrence rate was 0% at 12 months and 1.5% at 15 months. CONCLUSIONS: Breast pocket irrigation decreases bioburden, which may influence capsular contracture recurrence. We evaluated 3 varied applications of HOCl in revision aesthetic breast surgery and found a low capsular contracture recurrence rate and no adverse reactions. We plan to report our findings with HOCl in primary breast augmentation in the future, and other studies are being conducted on the efficacy of HOCl in aesthetic surgery.

Phlegmasia cerulea dolens secondary to an aortoiliac aneurysm.

Phlegmasia cerulea dolens is an uncommon entity. We present a case of phlegmasia cerulea dolens secondary to an aortoiliac aneurysm that compressed the common iliac vein. Catheter-directed thrombolysis was not considered to be a suitable option, because the patient needed an urgent fasciotomy. The aneurysm was treated with a bifurcated stent graft and the thrombosed veins were opened with pharmacomechanical thrombectomy and recombinant tissue plasminogen activator. The reopened iliac veins, including an aneurysmal external iliac vein, were stented and fasciotomy was performed. Pharmacomechanical thrombectomy can be performed with a low dose of recombinant tissue plasminogen activator and allows for subsequent surgery.

Propranolol attenuates hemorrhage and accelerates wound healing in severely burned adults.

INTRODUCTION: Propranolol, a nonselective ß-blocker, exerts an indirect effect on the vasculature by leaving α-adrenergic receptors unopposed, resulting in peripheral vasoconstriction. We have previously shown that propranolol diminishes peripheral blood following burn injury by increasing vascular resistance. The purpose of this study was to investigate whether wound healing and perioperative hemodynamics are affected by propranolol administration in severely burned adults. METHODS: Sixty-nine adult patients with burns covering ≥ 30% of the total body surface area (TBSA) were enrolled in this IRB-approved study. Patients received standard burn care with (n = 35) or without (control, n = 34) propranolol. Propranolol was administered within 48 hours of burns and given throughout hospital discharge to decrease heart rate by approximately 20% from admission levels. Wound healing was determined by comparing the time between grafting procedures. Blood loss was determined by comparing pre- and postoperative hematocrit while factoring in operative graft area. Data were collected between first admission and first discharge. RESULTS: Demographics, burn size, and mortality were comparable in the control and propranolol groups. Patients in the propranolol group received an average propranolol dose of 3.3 ± 3.0 mg/kg/day. Daily average heart rate over the first 30 days was significantly lower in the propranolol group (P < 0.05). The average number of days between skin grafting procedures was also lower in propranolol patients (10 ± 5 days) than in control patients (17 ± 12 days; P = 0.02), indicative of a faster donor site healing time in the propranolol group. Packed red blood cell infusion was similar between groups (control 5.3 ± 5.4 units vs. propranolol 4.4 ± 3.1 units, P = 0.89). Propranolol was associated with a 5 to 7% improvement in perioperative hematocrit during grafting procedures of 4,000 to 16,000 cm(2) compared to control (P = 0.002). CONCLUSIONS: Administration of propranolol during the acute hospitalization period diminishes blood loss during skin grafting procedures and markedly improves wound healing in severely burned adults. As burn patients require serial surgical interventions for motor and cosmetic repair, restricting blood loss during operative intervention is optimal.

Impact of anti-oxidant status and apoptosis on the induction phase of chemotherapy in childhood acute lymphoblastic leukemia.

This study aimed to evaluate oxidative stress and apoptosis in childhood acute lymphoblastic leukemia (ALL) at diagnosis and their impact on outcome at the end of the induction phase. Our study included 50 newly diagnosed children with ALL. Evaluation of oxidative stresses (malondialdehyde and total anti-oxidant capacity) was made at diagnosis and at the end of the induction phase. Apoptosis level was determined by fluorometric terminal deoxynucleotidyl transferase dUTP nick end labeling system for patients at diagnosis and after 1 week of treatment. Our study showed that there was increased oxidative stress at diagnosis and after treatment with chemotherapy. Apoptosis index was higher after 1 week of treatment with chemotherapy when compared to its level at diagnosis.

Phase II trial of capecitabine and weekly docetaxel for metastatic castrate resistant prostate cancer.

PURPOSE: Synergy is observed with the combination of capecitabine and docetaxel due to docetaxel mediated up-regulation of thymidine phosphorylase. A phase II trial was performed with the combination for metastatic, castrate resistant prostate cancer. MATERIALS AND METHODS: Eligible patients had metastatic, castrate resistant prostate cancer, no prior chemotherapy for metastatic disease and normal organ function. Docetaxel (36 mg/m(2) per week intravenously) on days 1, 8 and 15, and capecitabine (1,250 mg/m(2) per day in 2 divided doses) on days 5 to 18 were administered in 28-day cycles. The response was assessed every 2 cycles. Biomarker correlative studies were performed on blood dihydropyrimidine dehydrogenase, and the thymidine phosphorylase-to-dihydropyrimidine dehydrogenase and thymidine synthase-to-dihydropyrimidine dehydrogenase ratios in available prostate tumor tissue. RESULTS: A total of 30 patients with a median age of 69 years were enrolled in the study. We noted bone pain in 21 patients (70%), Gleason score 8 or higher in 18 (60%), measurable disease progression in 9, bone scan progression in 18 and prostate specific antigen progression in 22. Grade 3 or 4 neutropenia was seen in 3 patients and grade 3 hand-foot syndrome was found in 2. No treatment related deaths occurred. A prostate specific antigen response of 50% or greater decrease was observed in 22 patients (73%), of whom 9 (30%) had 90% or greater decrease. A partial response was noted in 5 of 9 patients (56%) with measurable disease. Median time to progression was 6.7 months (90% CI 4.2-7.7) and median overall survival was 22.0 months (90% CI 18.4-25.3). CONCLUSIONS: The combination was well tolerated and it demonstrated favorable response rates with durable remission and survival outcomes.
